DOCK-VALVE.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed January 29,1906. Serial No. 298.376.

To all whom it may concern:

Be it known that I, CARL TIBURTIUS, a subject of the German Emperor,residin at Wilhelmshaven, in the Grand Duchy of 1denburg and Empire ofGermany, have invented a new and Improved Dock-Valve, of which thefollowing is a specification.

My invention relates-to valves for the admission and discharge of waterfrom dry-do cks and the locks of canals and other structures where theadmission and discharge of large volumes of water in a comparativelyshort space of time is required; and the invention consists of a valveadapted to be raised and lowered by the water that it controls.

My invention further consists of a casing or housin for such valve andin the arrangement of t e channels and water-passages in the same.

The accompanying drawings illustrate embodiments of my invention, whichis further described in the specification and pointed out in the claims.

In the drawings, Figure 1 is a cross-section of a lock or dock wall,showing the valve and the water-passages controlled by said valve andthe passages and valve for controlling the position of the main valve.Fig. 2 is a modified form of valve and housing. Figs. 3 and 4 arecross-sections of the valves shown in Figs. 1 and 2.

Similar reference characters refer to like parts throughout the severalviews of the drawings.

In the filling and emptying of dry-docks situated above low tide and inthe filling of all dry-docks, in the filling and emptying ofcanal-locks, and under many other conditions it is often desirable tomove large quantities of water in the shortest space of time. Thepassages through which the water is to enter or escape are therefore oflarge size and the valves controlling them must correspond. Under usualcircumstances these valves, being under a heavy pressure, are difficultto move, expensive and complicated mechan- In the constructionillustrated in the drawings the mechanism employed is simple and themain valves operate practically automatically.

In Fig. 1 the wall of the lock or dock is shown in cross-section, thelevel of the water at the upper side being at 8 and at the lower side at9. Passages 15 and 16 are rovided for the discharge of the water from te upper to the lower side of the wall. This passage is normally closedby the valve A. The valve is shown constructed of angle framework andsheet-metal covering and provided with a chamber 2, by which it isrendered sufficiently buoyant to move easily. The lower end 1 contactswith the packing-ring 3, se cured to the material of the wall, whichring may be of Wood. The upper part of, the valve has aradially-projecting bottom portion 5, the outer edge of which isprovided with a depending flange that engages the packing-ring 4,carried by the rooved ring 6, secured to the wall. Small ro lers orwheels 17 serve to guide the movements of the valve.

Connected to the channel 15 and to the' space 7 above the valve is thebypass 14, the upper end of which may be closed by the valve 12. Theoverflow-pipe 13 is normally closed by this valve, which is soconstructed that when in its upper position it closes the pipe 13 andopens the passage 14, while when in its lower position it opens the pipe13 and closes the passage 14.

The operation of the mechanism is as follows: Under normal conditionsthe passage 14 is open, and the column of water in the space 7 is of thesame height as the water 8. The pressure upward in channel 16 actingagainst a smaller area to that against which the column in 7 presses,the valve will be held on its seat. Moving the small gate 12 downward toclose the passage 14 and open the pipe 13 permits the space 7 to empty.The upward pressure on the annular flange 5 raises valve, and the waterfrom 8 is permitted to pass through the channels 15 and 16. Changing thegate 12 to close the pipe 13 and open passage 14 permits water to fillthe space 7. Its pressure on the top of the valve soon becominggreater'than the upward pressure on the part 5 of the valve, the valveis pressed down onto its seats. Thus by the movement of the small valveor gate 12 the position of the large valve is regulated. The area of thelarge valve is of little moment so far as its control is concerned, itsaction depending entirely upon the height of the column of water in thespace 7 I In Fig. 2 the action of the water may be said to be reversed.The upper side of the wall is on the left, as before. The lower end ofthe valve has the usual air-chamber 3 1 and rests on packing-ring 23.The upper part of the valve is not so much larger than the lower part,as in Fig. 1, all the difference in diameter being a space suflicient toreceive the packing-ring 24 and the seat to hold it. The operation ofthis valve is as follows: Normally the pipe 33 connects the water 8above the wall to the interior chamber 27 above the valve, which willpermit the water in this space to rise to the height shown in Fig. 2.The difference in pressure between the column above the ring 24 and thatfrom below against the lower portion of the part 21 holds the valve onthe seat, as shown. By moving the valve or gate 32 so as to close thepassage 33 and open the passage 34, as shown in Fig. 2, the water in thespace 27 will be permitted to pass down through passage 34 into thechannel 36, slowly removing the excess of downward pressure. When thispressure is sufficiently removed, the upward pressure from channel 35will lift the valve and permit the water to pass through channel 36.Shifting the gate 32 will close the passage 34 and again admit the waterfrom the upper side of the Wall to the space 27 above the valve, forcingit to its seat.

The construction of the main valve will depend greatly on the size ofthe channels to be controlled. Good engineering will decide theconstruction best adapted to every case.

Having now explained my improvements, what I claim as my invention, anddesire to secure by Letters Patent, is

1. In a Wall for looks and docks having a chamber and a main passageconnecting said chamber with opposite sides of the wall, a valve tocontrol the flow of water through said passage, said wall also havingauxiliary passages, one extending from said chamber through said wall,and another extending from said chamber to said main passage, and meansto control the passage of water through both said auxiliary passages.

2. In a dock construction, the combination of a wall having a verticalchamber open at the top, and downward and laterally extending mainchannels, a valve adapted to open and close the connection between saidchannels and between said channels and the main chamber, and means tocontrol the position of said valve.

3. The combination of a wall constructed to separate bodies of water atdifferent levels provided with a central chamber open at the top andtransverse channels connecting with said chamber and with the bodies ofwater on either side of the wall, a valve in said chamber, a valve-seatsecured in said wall, and means to regulate the height of water in saidchamber, said valve being adapted to control the flow of water throughsaid transverse channels according to theheight of. water in thechamber.

4. The combination of a wall constructed to separate bodies of water atdifferent levels provided with a central chamber contracted at its lowerend, a valve-seat supported by the wall at the lower end of the chamber,a main valve adapted to engage said seat, a. second valve-seat mountedin said wall below the first, a second cylinder united tothe first andadapted to engage said second seat; said wall having a channel openingthrough one side thereof and extending up through said. valve-seats andconnecting with the central chamber, a second channel extending throughthe other side of the wall and connecting with the space between thevalve-seats, and auxiliary passages opening into the central chamber;and an auxiliary valve to open and close the auxiliary passages and thuscontrol the height of the water in the central chamber and thereby theposition of the main valve.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
